Features

Feature Description
Log configuration After you enable the Log Service for WAF feature, you can enable log collection for protected objects. Only after log collection is enabled for a protected object, WAF can collect and store the logs of the protected object. For more information about the fields that are included in WAF logs, see Fields in logs. For more information about how to enable log collection for a protected object, see Log collection.

You can modify log settings, such as the fields that are included in logs and the type of logs that you want to store. The log types are Full Log and Block Log. For more information, see Field settings.

Log query You can use query statements to query and analyze collected logs. For more information, see Query logs.

You can create alert rules based on query statements. After you create an alert rule, Log Service checks query and analysis results on a regular basis. If the query and analysis results meet a trigger condition that you specify in the alert rule, Log Service sends an alert notification. This allows you to monitor your service status in real time. For more information, see Configure an alert in Log Service.
